Application March 26, 1946, Serial No. 657,086 I 4 claims. (o1. 257-424) This invention relates to new and useful improvements and structural refinements in floor construction, and the principal object of the invention is to provide prefabricated sections adapted for positioning side by side to form the floor surface, said sections being equipped with suitable tubes for the circulation of a heating or cooling medium. This floor construction will thus readily lend itself for use in buildings which are heated or cooled through the floor rather than in the conventional manner and an additional object of the invention is, as aforesaid, to provide floor sections of novel and unique design, such as may be readily adapted in modern building construction.

A further object of the invention is to provide floor sections of the character described, in which the cooling or heating tubes may be easily connected, preferably, to form a continuous, coillike conduit.

Another object of the invention is to provide oor sections which may be quickly and conveniently interconnected with one another.

An additional object of the invention is to provide floor sections which are of simple construction and which will readily lend themselves to prefabrication.

With the above more important objects in View, and such other objects as may become apparent as this specification proceeds, the invention consists essentially of the arrangement and construction of parts as illustrated in the accompanying drawings, in which:

Figure l is a top plan view of the invention.

Figure 2 is a cross-sectional vieWtaken in the plane of the line 2 2 in Figure 1.

Figure 3 is a cross-sectional view, taken in the plane of the line 3 3 in Figure l.

Figure 4 is a fragmentary plan view, illustrating the manner in which the cooling or heating tubes are connected.

Figure 5 is an enlarged fragmentary sectional view taken on the line 5 5 of Figure 1 and in the direction of the arrows.

Like characters of reference are used to desig- V nate like parts in the specication and throughconstitute air pockets, or in other words, insulating chambers for preventing the dissipation of heat or cold through the underside of the floor.

Heating or cooling tubes 'I are imbedded into each of the sections 5, these tubes being substantially of a U-shaped conguration and the ends thereof extending to the edges of the sections, as will be clearly apparent from the accompanying drawings.

The several sections are interconnected in a manner best illustrated in the accompanying Figure 3, wherein the sections are formed on the underside adjacent the edges thereof with suitable recesses 8, and the angle brackets 9 are secured in these recesses by the bolts or screws I0. The downturned portions I I of the brackets 9 are formed with suitable apertures adapted to receive a draw bolt I2 and it will be noted that the sections may thus be iirmly and securely connected together by tightening the various draw bolts.

The adjacent ends of the tubes 1 are connected together by means of the couplings I3, these being of a substantially elliptical cross-sectional configuration and provided with longitudinally extending axial bores I4. The ends of the tubes 'I are formed with chamfered bores as indicated at I5 and the ends of the couplings co-act with these chamfered bores upon the tightening of the bolts I2. It Will be apparent that the various connections of the tubes are made simultaneously by simply inserting the couplings I 3 in position and tightening said bolts.

As is best illustrated in the accompanying Figure 1, the several tubes 'I are arranged for connection in series to form a continuous coillike conduit, the ends I6 of which are in turn, connected to the supply and return of the heating or cooling medium. This latter connection is accomplished by suitable couplings I'I and extension pipes I8, and an air vent I9 may be installed, preferably in the return line, to avoid formation of air pockets in the floor tubing.

In view of the foregoing, it is believed that the operation of the invention will be readily understood and. accordingly, further explanation thereof is considered unnecessary.

While in the foregoing there has been shown and described the preferred embodiment of this invention it is to be understood that minor changes in the details of construction, combination and arrangement of parts may be resorted to Without departing from the spirit and scope of the invention as claimed.

What I claim as my invention is:

1. In a floor construction, a pair of sections,

each section having a pair of brackets secured thereto and the brackets of one section being spaced slightly from the brackets of the other section when confronting edges of said sections are disposed against each other, means for locking said brackets adjacent each other and for pulling said sections against each other, tubes embedded in each of said sections for conducting uid therethrough, means for interconnecting said tub'es, -said interconnecting :means including sleeves of substantially ellipsoidal form, and said tubes having bores therein with the end portions of said bores bevelled, and said substantially ellipsoidal sleeves lockingly Yengaging the bevelled end portions of said bores, whereby when said sections are locked together *the end portions of said sleeves are locked iin thebevelled end portions of said bores.

2. A floor construction comprising a'plurality of sections, each section having an edge which 'isadapted to engage an edge of a confronting sec'- tion, tubes in'each of said sections for conducting 4iiuid therethrough, said 'tubes lhaving Vbores which are bevelled vat lthe ends thereof, sleeves having theirexterior surfaces smoothly curved at the "ends Athereof 'and ldisposed in the bevelled Aends 'of said bores, and means carried by said sections adjacent butspace'dfrom said edges 'thereof for attaching said sections together and for pulling land locking said -sleeves -in 'said bevelled bores.

3. -fA oor lconstruction 'comprising Aa plurality of kSections,fe'achsec'tion' 'having an edge, tubes secured to each of said sections for conducting 'uid Vthrough the sections, bores in said tubes and having bevelled portions at the'ends thereof, 'sleeves which are substantially'elipsoidal in form, fthe ends of said Sleeves 'beingdisposed in confronting bevelled portions at said edges of said sections, means carrie'dby saidsections'adjacent but spaced -from Sad *edges ro'f said sections for Satta'chng said sections and lfor pulling-said 'sections together to *thereby lock the endsio'f said '4 sleeves in the bevelled portions of said tubes, and each section being provided in the underside and between the tubes thereof with air conducting channels Which communicate With each other when said sections are xed together by said attaching means to constitute air insulation means.

4. A oor construction comprising a pair of I sections,4 each section having a confronting edge,

:tubes embeddedin eachofsaid :sections to conduct uid through these sections, said tubes hav- .ving bores which are bevelled at the ends thereof tb form seats, sleeves, said sleeves being substantiallyelipsoidal, the ends of said sleeves being disposed in..confronting bevelled end portions of said bore`s,^m'eans carried by said sections adjawcent -Abut spaced ffrom the confronting edges thereof for attaching and pulling said sections together and for locking said sleeves in said seats, and said tubes being composed of a plurality 'of substantially U 'shaped .members vv.where- 'by each tube risvprovided -with two end portions which confront'two-'end vportions of aco-nfront- 'ing'tube 'WILBERT F.
